Charlie Sheen is clearly not learning his lesson. The 'Two and Half Men' star is leaving Los Angeles Wednesday on a tropical vacation with his wife, his live-in porn star girlfriend and another woman, RadarOnline.com is exclusively reporting. Seems the TV star forgot that he's supposed to be in rehab and that his show is shut down as it waits for him to finish treatment.

RadarOnline broke the news earlier Wednesday that Sheen's ex-wife, Brooke Mueller, moved back in with the actor this past weekend. Also shacking up with them are porn star Bree Olson and "nanny" Natalie Kenly. And now, the whole crew is reportedly headed on a vacation to a private tropical island.

"Just when you think Charlie Sheen can't do anything else to make you shake your head in amazement, he finds a way to top himself," said David Perel, RadarOnline creator and executive vice president. We couldn't agree more.

"Charlie is back to his old self -- and that's not a good thing," a source told RadarOnline exclusively. "So much for rehab at home. He took off with the girls on Wednesday." The source added that while Kenly has been described as the "nanny," she's not.

"Charlie talked about building a porn family, and now he's got these three women all living with him and taking off on vacation with him," the source explained.

Though Mueller has reportedly told friends that she and Sheen are just friends, the sources said, "That's not the case at all."

And porn star Olson tweeted on Tuesday, "Going to a tropical wonder for a little while to relax with friends :) minimal tweets so hold tight! Be home soon babies!"

UPDATE: 'Two and a Half Men' has shut down after a day of intense Charlie Sheen rants. Watch PopEater discuss what's next for Sheen with RadarOnline.com:

to Charlie Sheen: It's a damn shame that someone with everything aperson could want (loving family,friends who care about you,not tomention fame and fortune) would throw it all down the toilet the wayyou do. If you were in front of me I'd probably kick your butt! I am a60 year old woman who fights just to make under 500.00 a month becauseI can't find a full time job. and you , you spoiled brat throw it awayon hookers,drugs and crap lie that. I wish I had your talent youstupid f**k I sure wouldn't throw it away on stiff one! You just psssme off! You probably won't even know you fans feel this way.

What wife? He's divorced. TMZ also reported he was near death after theNYC bender. The show is also going back into production in the next few days. He'll be in two places at the same time? This article is a piece of crap.

Maybe he ought to live in the middle east and have a harem!His estranged wife moved back in with him this past weekend, how much did that cost him? Did he buy her a car and anything else?She's as **** as he is!!

Shut the show down already! He has no intention of cleaning himself up and besides, he's just like lindsay, money talks, so he doesn't have to worry about consequences. How pathetic of a human being. Even more pathetic is Brooke. How could she possibly move back in with a man who put a knife to her throat and threatened to kill her? What happened? Did she have the restraining order removed? Let them all rot in hell. They are nothing, so let's move on in the entertainment world, because he is not entertainment!

leave the guy alone . hes an adult, he can make his own decisions . hes not hurting anyone but himself . if you don't like him .... don't watch the show its that simple . what is it with this movement in america , that if people don't like your lifestyle you should lose your job and career? if you do your job and produce thats all that should matter . nothing else .

This guy is gross. His wife is a nut for moving back in with him. She must enjoy watching him having sex with the hookers. His show is being on hold, think of all the people who work specifically with him.Charlie is incredibly selfish,

Debauchery, Likely STD's, Possibly AIDS. Likely abortion/murder of his children. Talent/Looks/Opportunity blown away with Coke and rebellion.This is a man, gifted by his creator, who is about to be consumed by the Depths of Hell. And my heart breaks for him.
